I spoke with the National Weather Service office this morning. They are concerned with flash freezing Saturday night through Sunday. Please be prepared and expect extreme conditions coming over the passes this weekend. Below is the text discussion:
Saturday night into Sunday...Weather models continue to advertise a potent COLD FRONT that will push southwards out of Canada. Marias Pass may see deteriorating conditions Saturday night with moderate to heavy snowfall and gusty easterly winds. Temperatures there will drop from the 30s to the teens. Conditions along highway 2 from West Glacier to the pass could get quite slick and snow-covered by daybreak Sunday. The Kalispell area could see snow develop after midnight Saturday night and roads could also become slick by Sunday morning.
As the FRONT sags south across west-central Montana on Sunday, intense showers of rain, snow and possible GRAUPEL changing to wet snow. With road temperatures above freezing the impacts in the lower valleys will mainly be reduced VISIBILITY and gusty winds. Strong gusty northerly winds with 2 to 3 foot wave heights are possible over Flathead Lake negatively impacting Mack Days there. Places like Evaro Hill on highway 93 could become slick by the evening hours if snow continues to fall there while other mountain passes along the Continental Divide will see slick conditions as well. Confidence is good for the forecast of slick roads along the Divide and for gusty winds on Flathead Lake, but becomes fair to poor for how much snow will fall in the valleys of western Montana.
